looking for work (Ottawa)

I am in the early stages of making the move from Dublin, Ireland, to Canada. Preferably Ottawa. I am a pre school teacher, working for the last 8 years, with experience, both on a personal and professional level, with special needs children. I have been applying to everything I see on different employment sites with no luck. I would work in any sector, but would prefer pre school or nanny. I have Garda (irish police) clearance and first aid and all childcare qualifications. I would be very, very grateful if anyone here knows of anyone hiring or anyone looking for a lovely, kind, Irish nanny/childminder!:)

I was told by the visa office there were loads of nanny jobs, but obviously it's easier to get a visa if there is a job to go to!
